2'0 all whom it TIMLZ/ concern.-

Be it known that I, EMILE LnoN PAUL TU- RENNE, civil engineer, a citizen of the Republic of France, residing at 82 Rue Curial, Paris, France, have invented an Improvement in M0- tors Operating with Heavy Hydrocarbons, of which the following is a specification.

This invention has for object a special arrangement of explosion-engine for heavy hydrocarbons, such as petroleum, and in which a very reduced consumption of oil is secured, while at the same time all clogging is prevented. The essential characteristic of this arrangement consists in that the different parts of the motor are so devised as to secure in the combustion or explosion chamber an excess of heat of which advantage is taken for vaporizing a certain volume of water which is sent into the motor at the same time as the air which is necessary for running the motor, the conditions being such that the air enters the cylinder of the motor at a very high temperature and the water in the state of steam before they are mixed with the hydrocarbonvapor.

In the drawings, Figure 1 is a vertical section along the axis of as much as is necessary of an ordinary petroleum-motor or a lamppetroleum motor constructed according to the present invention for a clear understanding of the manner in which it is carried into effect. Fig. 2 is a horizontal section along 2 2, Fig. l.

a is the cylinder of the motor in which the piston 6 moves and is provided with a usual jacket a for circulating water.

0 is the breech of the motor, wherein water also circulates. Within this breech is formed the explosion-chamber d, and into the latter opens the mechanically operated exhaustvalve 0.

The ignition in the motor can be effected either by means of a tube heated by any kind of lamp or, as in the arrangement shown in the drawings, by spontaneous ignition by means of an ignitingtube f, which being placed in the explosion-chamber is heated by the successive explosions of the motor and onto which liquid petroleum is projected by means of the spray-injectorg, Fig. 2. In both cases the proportions of the different parts of the motor are such that during operation an excess of heat is produced which if not absorbed would raise the igniter f to too high a temperature. Now in the arrangement herein described instead of allowing the excess of heat to accumulate or of leading it away without producing any useful efiect advantage is taken of it at once for vaporizing a certain volume of water which is then sent into the motor at the same time as the air necessary for the running of same. For this purpose a waterpipe it opens into the valvebox 2'', through which the air required for running the motor is admitted to the cylinder and the air and water after having passed through the inlet valve or valves j enter during the suction-stroke of the piston b the baffled or nonbaflied tube k, placed in the explosion-chamber d. Here in consequence of the very hot walls with which it is in contact the water is transformed into steam in such a manner that after having passed through the tube the air and water mixed togethcrenter at m the cylinder a of the motor, the first at a very high temperature and the second as steam previous to their being mixed with the petroleum-va- This device shows the advantage that por. for a given power the quantity of hydrocarbon required for running the motor can be diminished owing to the power of expansion of the water-vapor produced, and besides all clogging is prevented.

- It is evident that the invention is not strictly limited to the exact construction described above and shown in the drawings and that the arrangement, the shape, and proportions of the passage k and explosion-chamber (Z may vary according to the exigencies of practical use and according to the particular cases which the motor may be applied. The motor could besides be constructed on a horizontal plan as well as on a vertical plan and could comprise, if necessary, several cylinders. It will also be seen that instead of passing the air and the water through the same tube they could pass through two separate tubes and could enter through two separate inlet-valves.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a motor of the kind described, the combination, with a cylinder in which a piston is actuated, an explosion-chamber,- means for injecting a charge of finely-divided liquid fuel into this chamber and means for producing the ignition of the charge, of a tube or channel passing through said explosion-chamber and communicating with the cylinder, a chamber for air and water, a valve between this chamber and the said tube, means for admitting air to the chamber for air and water, and means for supplying the said chamber with Water, the said valve opening during the suction-stroke of the piston into the cylinder for the purpose of causing the mixed air and the Water to pass from the said chamber for air and Water to the said tube, substantially as described andshown and for the purposes set forth.

2. In a motor of the kind described, the combination, With a cylinder, a piston in this cylinder and an explosion-chamber provided with devices for injecting therein finely-divided liquid fuel and means for ignition, of a baffied or non-baffled tube or channel placed in the said chamber and in communication with the said cylinder, a valve-box connected to the said tube, means for supplying this box With air and Water, an inlet-valve in the said valvebox, Which opens during the suction-stroke of the piston to allow the air and Water to pass in a mixed condition from the valve-box through the said tube to the said cylinder, substantially as described and shown, and for the purposes set forth.

3. In a motor of the kind described, the combination with a cylinder, a piston in this cylinder and an explosion-chamber, of a tube or channel placed Within the explosion-chamber and communicating with the cylinder; a valve for the admission of air to the said tube and a valve for the admission of Water to the said tube, the above said valves for the admission of air and Water opening, during the suctionstroke of the piston, into the cylinder for letting air and water enter the said tube, Where the air and the water are mixed and heated and whence they-pass into the cylinder, the first at a very high temperature and the second in the state of steam; means for injecting at the same time a certain quantity of liquid fuel into the said explosion-chamber so as to produce with the air and steam an explosive mixture and an ignition device for producing the i gnition of the explosive charge. substantially as described and for the purposes set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
